Molecular vibrations and quantum tunneling may link ligand binding to the function of pharmacological receptors. The well‐established lock‐and‐key model explains a ligand's binding and recognition by a receptor; however, a general mechanism by which receptors translate binding into activation, inactivation, or modulation remains elusive. The Vibration Theory of Olfaction was proposed in the 1930s to explain this subset of receptor‐mediated phenomena by correlating odorant molecular vibrations to smell, but a mechanism was lacking. In the 1990s, inelastic electron tunneling was proposed (...) as a plausible mechanism for translating molecular vibration to odorant physiology. More recently, studies of ligands’ vibrational spectra and the use of deuterated ligand analogs have provided helpful information to study this admittedly controversial hypothesis in metabotropic receptors other than olfactory receptors. In the present work, based in part on published experiments from our laboratory using planarians as an experimental organism, I will present a rationale and possible experimental approach for extending this idea to ligand‐gated ion channels.

This commentary suggests: (1) experimentalists must expand their subject pools beyond university students; (2) the pollution created by deception would not be a problem if experimentalists fully used non-student subjects; (3) one-shot games remain important and repeated games should not ignore social learning; (4) economists need to take better control of context; and (5) using computers in experiments creates potential problems.

Defense of Scientific Hypothesis: From Reproducibility Crisis to Big Data sets out to explain and defend the scientific hypothesis. Alger's mission is to counteract the misinformation and misunderstanding about the hypothesis that even seasoned scientists have concerning its nature and place in modern science. Most biological scientists receive little or no formal training in scientific thinking. Further, the hypothesis is under attack by critics who claim that it is irrelevant to science. In order to appreciate and (...) evaluate scientific controversies like global climate change, vaccine safety, etc., the public first needs to understand the hypothesis. Defense of Scientific Hypothesis begins by describing and analyzing the scientific hypothesis in depth and examining its relationships to various kinds of science. Alger then guides readers through a review of the hypothesis in the context of the Reproducibility Crisis and presents survey data on how scientists perceive and employ hypotheses. He assesses cognitive factors that influence our ability to use the hypothesis and makes practical and policy recommendations for teaching and learning about it. Finally, Alger considers two possible futures of the hypothesis in science as the Big Data revolution looms: in one scenario, the hypothesis is displaced by the Big Data Mindset that forgoes understanding in favor of correlation and prediction. In the other, robotic science incorporates the hypotheses into mechanized laboratories guided by artificial intelligence. But in his illuminating epilogue, Alger envisions a third way, the Centaur Scientist, a symbiotic relationship between human scientists and computers. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:My Story:Evolving ObesitiesAnonymous OneI am a 66–year–old Caucasian woman. I have always had, either in perception or fact, a “weight problem.” In my childhood and early teens when my weight was within the normal range, I felt fat and was always trying to lose weight. After gaining weight in college, I had a weight problem in body as well as mind. Weight concerns have consumed much of my energy (...) over the years. I have spent most of my life evolving toward a healthy way to manage my weight.Act 1: Obesity as MetaphorI can’t remember ever not feeling fat. Growing up I felt humiliated and shamed by my body, even though I was not overweight, just bigger than my peers, with a pear shape and heavy legs, thighs, and ankles. In high school my BMI, although not used at the time as a measuring tool, was 22.8. Yet despite these facts, I was made to feel fat.In my family being overweight was tantamount to sin. My father and sister were tall and skinny; my mother was petite and shapely. I took after another genetic code—the dumpy ones with knocked knees—the grotesque branch of the family tree. Hand–me–downs from my sister were supposed to fit me, but we were too different, and the difference was not celebrated.Other things were at play, a perfect storm of conditions that contributed to my feelings of worthlessness. I really shouldn’t have been born. The earth should have opened up and swallowed me. Of course I was not conscious of reasons for these feelings at the time. That awareness came later. But these feelings of loss, grief, terror, and terrible wrongness were the context of my struggles over the years.I developed a pattern of binge eating, which satisfied two contradictory impulses: my need to nurture myself combined with my desire to punish myself. The intensity of a binge–eating episode was also an avenue for rage. I was young so the extra calories didn’t result in weight gain, but the behavior had begun to take root.Stepping on the scale was like the final judgment. The scale did not measure weight; it measured value. I would see the number, as would the person weighing me, and my failure, as a person, would be evident. My secret shame would become public. I would be declared guilty for the worthless grub that was me.Nothing else mattered: that I was an A student; that I was kind and compassionate; that I had friends. These facts had no bearing. All that counted was the number on the scale. That number sent a shudder of condemnation down to my very soul. That number threatened to hurl me into a bottomless abyss from which I could not escape.I avoided being weighed. I was a very obedient youth, with an exaggerated respect for authority drilled into me by my father. The one time I ever cut class was in high school. I skipped health class where I had heard we would be weighed.The situations when I could not avoid being weighed confirmed my worst fears. Before one gym class we were publicly weighed in [End Page 96] assembly–line fashion. As I stepped off the scale my gym teacher yelled out “Diet” for all to hear. Doctors who knew nothing about me, to whom I had been sent for various required physicals, told me to lose weight.In the mysterious and internally logical way that the mind works, my weight became a metaphor for all that was reprehensible in me. With no comprehension of why I was so unhappy, it was easy for me to fixate on my weight. It was too horrible to contemplate that I was the problem. The problem with me was my size, my body.As I look back now, I am angry that because of its shape, this perfectly wonderful body was judged as wrong, and that there was no compassionate voice loud enough to contradict this message. But at the time I felt no anger. To feel anger over being made to feel bad requires self–respect... (shrink)

Many philosophers and psychologists now argue that emotions play a vital role in reasoning. This paper explores one particular way of elucidating how emotions help reason which may be dubbed ?the search hypothesis of emotion?. After outlining the search hypothesis of emotion and dispensing with a red herring that has marred previous statements of the hypothesis, I discuss two alternative readings of the search hypothesis. It is argued that the search hypothesis must be construed as (...) an account of what emotions typically do, rather than as a definition of emotion. Even as an account of what emotions typically do, the search hypothesis can only be evaluated in the context of a specific theory of what emotions are. 1 Introduction 2 The search hypothesis of emotion 3 A red herring: the frame problem 4 The search problem 5 Two readings of the search hypothesis 6 Two final remarks 7 Conclusion.

Background:Moral courage is defined as courage to act according to one’s own ethical values and principles even at the risk of negative consequences for the individual. In a complex nursing practice, ethical considerations are integral. Moral courage is needed throughout nurses’ career.Aim:To analyse graduating nursing students’ moral courage and the factors associated with it in six European countries.Research design:A cross-sectional design, using a structured questionnaire, as part of a larger international ProCompNurse study. In the questionnaire, moral courage was assessed with (...) a single question (visual analogue scale 0–100), the questionnaire also covered several background variables.Participants and research context:The sample comprised graduating nursing students (n = 1796) from all participating countries. To get a comprehensive view about graduating nursing students’ moral courage, the views of nurse managers (n = 538) and patients (n = 1327) from the same units in which the graduating nursing students practised were also explored, with parallel questionnaires.Ethical considerations:Ethical approvals and research permissions were obtained according to national standards in every country and all participants gave their informed consent.Results:The mean of graduating nursing students’ self-assessed moral courage was 77.8 (standard deviation 17.0; on a 0–100 scale), with statistically significant differences between countries. Higher moral courage was associated with many factors, especially the level of professional competence. The managers assessed the graduating nursing students’ moral courage lower (66.5; standard deviation 18.4) and the patients slightly higher (80.6; standard deviation 19.4) than the graduating nursing students themselves.Discussion and conclusions:In all countries, the graduating nursing students’ moral courage was assessed as rather high, with differences between countries and populations. These differences and associations between moral courage and ethics education require further research. (shrink)

The Meditations of Marcus Aurelius are treasured today--as they have been over the centuries--as an inexhaustible source of wisdom. And as one of the three most important expressions of Stoicism, this is an essential text for everyone interested in ancient religion and philosophy. Yet the clarity and ease of the work's style are deceptive. Pierre Hadot, eminent historian of ancient thought, uncovers new levels of meaning and expands our understanding of its underlying philosophy. Written by the Roman emperor for his (...) own private guidance and self-admonition, the Meditations set forth principles for living a good and just life. Hadot probes Marcus Aurelius's guidelines and convictions and discerns the hitherto unperceived conceptual system that grounds them. Abundantly quoting the Meditations to illustrate his analysis, the author allows Marcus Aurelius to speak directly to the reader. And Hadot unfolds for us the philosophical context of the Meditations, commenting on the philosophers Marcus Aurelius read and giving special attention to the teachings of Epictetus, whose disciple he was. The soul, the guiding principle within us, is in Marcus Aurelius's Stoic philosophy an inviolable stronghold of freedom, the "inner citadel." This spirited and engaging study of his thought offers a fresh picture of the fascinating philosopher-emperor, a fuller understanding of the tradition and doctrines of Stoicism, and rich insight on the culture of the Roman empire in the second century. Pierre Hadot has been working on Marcus Aurelius for more than twenty years; in this book he distills his analysis and conclusions with extraordinary lucidity for the general reader. (shrink)

In this paper, I shall set out the pros and cons of assigning legal personhood on artificial intelligence systems under civil law. More specifically, I will provide arguments supporting a functionalist justification for conferring personhood on AIs, and I will try to identify what content this legal status might have from a regulatory perspective. Being a person in law implies the entitlement to one or more legal positions. I will mainly focus on liability as it is one of the main (...) grounds for the attribution of legal personhood, like for collective legal entities. A better distribution of responsibilities resulting from unpredictably illegal and/or harmful behaviour may be one of the main reasons to justify the attribution of personhood also for AI systems. This means an efficient allocation of the risks and social costs associated with the use of AIs, ensuring the protection of victims, incentives for production, and technological innovation. However, the paper also considers other legal positions triggered by personhood in addition to responsibility: specific competencies and powers such as, for example, financial autonomy, the ability to hold property, make contracts, sue.

Paleobiologists often provide simple narratives to explain complex, contingent episodes. These narratives are sometimes ‘one-shot hypotheses’ which are treated as being mutually exclusive with other possible explanations of the target episode, and are thus extended to accommodate as much about the episode as possible. I argue that a provisional preference for such hypotheses provides two kinds of productive scaffolding. First, they generate ‘hypothetical difference-makers’: one-shot hypotheses highlight and isolate empirically tractable dependencies between variables. Second, investigations of hypothetical difference-makers provision explanatory (...) resources, the ‘raw materials’ for constructing more complex—and likely more adequate—explanations. Provisional preferences for simple, one-shot hypotheses in historical science, then, is defeasibly justified on indirect—strategic—grounds. My argument is made in reference to recent developments regarding the K–Pg extinction. (shrink)

John Damascene, one of the most productive Greek theologians of the Middle Byzantine era, also composed a treatise on the Trisagion hymn, or how it should be sung correctly and why; a text that has been little discussed in contemporary scholarship. The present paper provides an overview of the work – with special reference to the notion of identity in John’s description of the Trinitarian doctrine. It also examines the treatise especially in the context of anti-heretical polemics. The author argues (...) that John’s approach to the question of the correct way of singing the hymn is gentle: instead of using pejorative language, he even praises the object of his reproach.

The Optimal Innovation Hypothesis, following from the Graded Salience Hypothesis, is being reviewed and revisited. The attempt is to expand the notion of Optimal Innovation to allow it to apply to both stimuli’s coded meanings as well as their noncoded, constructed interpretations. According to the Optimal Innovation Hypothesis, Optimal Innovations, when devised, will be more pleasing than nonoptimally innovative counterparts. Unlike such competitors, Optimal Innovations deautomatize familiar coded alternatives, which invoke unconditional responses alongside novel but distinct ones, (...) allowing both responses to interact. Conversely, the Revised Optimal Innovation Hypothesis, introduced and tested here, follows from the Defaultness Hypothesis. It posits that both default lexicalized meanings and default constructed interpretations might be qualifiable for Optimal Innovation once they are deautomatized by nondefault, context-dependent counterparts. Such nondefault Optimal Innovations will be pleasing, more pleasing than default and nondefault counterparts not qualifiable for Optimal Innovation. Results of two experiments support the Revised Optimal Innovation Hypothesis, while further corroborating the Defaultness Hypothesis. (shrink)

How do humans ‘register’ God: attain knowledge or revelation of God? Analysis is familiar in terms of explanatory hypothesis, necessity, authority and commitment. However individuals speak also of ‘experience’ or ‘consciousness’ of God/Christ/grace – received widely, not just by an esoteric few. But may we properly hold that people can be cognitively aware of God?Undoubtedly such speech has problematic aspects. Not only do psychosis, self‐deception, gullibility recur. Commentators are liable to enlist what may be termed the A‐conceptual Lucidity picture, (...) which critically fails.Various positions urged by thinkers rule out by definition the very possibility of cognitive awareness of God. Some analysts assert: a person’s experiencing x is constituted throughout by the person’s use of concepts in toto reached previously and independently. But, why adopt any a priori dismissiveness?We should favour a portrayal of people’s epistemic situation respecting God called the Consciousness Portrayal. Phrases therein include: ‘God’s gracious, guiding activity’; ‘a person’s access to God’; ‘attentive consciousness/conceptualization/knowledge of God’; ‘diverse levels or modes of consciousness’; ‘God’s guidance in a person’s creatively picking out concepts’; and ‘“cognition” which, as regards meaning, is not just a function of calculative reasoning’. Alertness to usage in non‐religious contexts aids our finding the religious phrasing intelligible. The Portrayal is approachable from an internal and external angle.Opponents’ challenges to the Portrayal invoke some broad epistemological theses, often pronounced intrinsic to ‘rationality’. But we fittingly espouse certain contrasting epistemological views. And these prove to fortify the Consciousness Portrayal. (shrink)

A common view in face recognition research holds that there is a stored representation specific to each known face. It is also posited that semantic or memory-based information cannot influence low-level face processing. The two experiments reported in this article investigate the nature of this representation and the flow of face information processing. Participants had to search for a particular primed face among other faces. In Experiment 1, the search was done in a context where distractors had either a different (...) degree of fame or the same degree of fame. In Experiment 2, the target face was primed either with semantic information or without any information. Both experiments demonstrated that increasing the display set size lengthened face detection time. However, the lengthening was a function of face fame. The search context also had an effect on the slope of the famous face detection. The results are explained in terms of the idea that face representations are reconstructed and that high- and low-level information are integrated into the processing. The integration process is not a conscious one. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Report on the Ninth European Network of Buddhist-Christian Studies Conference:"Hope: A Form of Delusion? Buddhist and Christian Perspectives"Elizabeth J. Harris, President of the NetworkCan we hope in a world that is shot through with suffering? Should hope be shunned as a form of attachment? Should we affirm our hope or let go of it? And, if we embrace hope, what should we hope for and what can inspire us? (...) Between sixty and seventy people, from sixteen countries, came together to address questions such as these at the ninth conference of the European Network of Buddhist-Christian Studies, held in glorious weather at Liverpool Hope University in England, between 30 June and 4 July 2011.At the heart of the conference were ten keynote presentations on five crucial aspects of the theme of hope: "Hope and the Critique of Hope," "Hope in Pastoral Situations," "Embodiments of Hope," "Hope in Situations of Hopelessness: Engaged Buddhism and Liberation Theology," and "Eschatologies of Hope." Dr. Sybille Fritsch-Oppermann (Church of Southern Hesse) gave the introductory lecture, which suggested that hope can be seen both as a utopian ideal within and beyond living religions, and a working hypothesis, through which humans can strive toward truth and transcendence.Each theme was addressed from a Buddhist and a Christian perspective, followed by a plenary to enable dialogue between the speakers, and between speakers and participants. Addressing the first theme, "Hope and the Critique of Hope," from a Buddhist perspective, Richard Gombrich (Balliol College, Oxford) robustly argued that hope was not a category relevant to Theravada Buddhism, distinguishing between hope and confidence, and hope and expectation. Werner Jeanrond (Glasgow University), taking the Christian perspective, suggested that a critical theology of hope—an inter-hope dialogue—is necessary, within a critique of other key concepts such as salvation, faith, and love. [End Page 135]Within the session titled "Hope in Pastoral Situations," Dr. Hiroshi Munehiro Niwano (Rissho Kosei-kai, Japan) focused on Rissho Kosei-kai's pastoral work, most movingly its response to the recent earthquake and tsunami in Japan. Notto Thelle (Oslo University), speaking from a Christian viewpoint, sensitively explored pastoral situations caused by life experiences that seem to question and make a mockery of hope, drawing on decades of Buddhist-Christian encounter. Peggy Morgan (Mansfield College, Oxford), addressing the third theme, "Embodiments of Hope," concretized her brief by focusing on a contemporary embodiment of hope capable of emboldening Christians: Rosemary Radford Ruether and her listening dialogue with Buddhism. Mitsuya Dake (Ryukoku University, Japan), on the other hand, chose Amida Buddha as his empowering embodiment of the wisdom, compassion, and non-dualism that lies at the heart of Buddhism, focusing on Shinran's understanding.The theme "Hope in Situations of Hopelessness" was opened to the public in an evening session. Sallie King (James Madison University, USA), using examples such as the Sarvodaya Movement in Sri Lanka and the Dalai Lama's peace work, argued that Buddhism is "loaded" with hope, from an Engaged Buddhist perspective. Buddhist hope, at one level, is an amalgam of acceptance, lawful change, and effort. At another level, it is the conviction that everyone has the potential to change and that truth has power. Sathianathan Clarke (Wesley Theological College, Washington, D.C.) movingly examined Dalit liberation theology, suggesting that hope within this context could be seen as a proxy topos that extends faith into life, an alter-wisdom where love can enrich life, and an energy, a verb, leading to transformative action.Addressing the last theme, "Eschatologies of Hope," Anthony Kelly (Australian Catholic University) recognized a contemporary crisis of hope and, distinguishing between hope as an emotion and hope as a virtue, explored a paradox: that Christian hope is rooted in the resurrection of the crucified Jesus but that this event is described in a varied rhetoric of negations. Justin Ritzinger (Oberlin College, USA), noting that endings are hard to find in Buddhist literature, examined the coming of Maitreya, the future Buddha, as a possible candidate for a Buddhist eschaton. He concluded that the similarities to Christian eschatology are superficial, with the exception of a contemporary reinvention of the Maitreyan tradition in China.In addition to invited keynote speakers, a...

The subject of this essay is the dependence of evidential relations on background beliefs and assumptions. In Part I, two ways in which the relation between evidence and hypothesis is dependent on such assumptions are discussed and it is shown how in the context of appropriately differing background beliefs what is identifiable as the same state of affairs can be taken as evidence for conflicting hypotheses. The dependence of evidential relations on background beliefs is illustrated by discussions of the (...) Michelson-Morley experiment and the discovery of oxygen. In Part II, Hempel's analysis of confirmation and the contrasting model of theory acceptance provided by philosophers such as Kuhn and Feyerabend are discussed. It is argued that both are inadequate (on different grounds) and the problems addressed by each are shown to be more satisfactorily approached by means of the analysis developed in Part I. In Part III, it is argued that if there are objective criteria for deciding between competing theories, these cannot be simply that one theory has greater evidential support than another. Finally, some further methodological questions arising from the analysis are mentioned. (shrink)

The study of social justice asks: what sorts of social arrangements are equitable ones? But also: how do we derive the inequitable arrangements we often observe in human societies? In particular, in spite of explicitly stated equity norms, categorical inequity tends to be the rule rather than the exception. The cultural Red King hypothesis predicts that differentials in group size may lead to inequitable outcomes for minority groups even in the absence of explicit or implicit bias. We test this (...) prediction in an experimental context where subjects divided into groups engage in repeated play of a bargaining game. We ran 14 trials involving a total of 112 participants. The results of the experiments are statistically significant and suggestive: individuals in minority groups in these experiments end up receiving fewer resources than those in majority groups. Combined with previous theoretical findings, these results give some reason to think that the cultural Red King may occur in real human groups. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Commentary on “Multiple Personality and Moral Responsibility”Daniel W. Shuman (bio)Stephen Braude’s essay, “Multiple Personality and Moral Responsibility,” discusses a number of important issues about the moral and legal responsibility of persons diagnosed with multiple personality disorder (MPD), known in DSM-IV as Dissociative Identity Disorder (DID). One issue that is fundamental to this debate, which Braude does not address, however, is the empirical reality underlying the debate. Does MPD/DID exist? (...) A prerequisite to a debate about the legal consequences of MPD/DID is legally sufficient proof of its existence and its behavioral consequences.Proof that MPD/DID exists, its impact on legal standards of responsibility, and that the defendant suffers from it, must come from expert testimony; it is not part of the common knowledge or experience of the typical judge or juror. Courts are, however, increasingly, unwilling to assume that because an expert has impressive qualifications, he or she will necessarily present scientifically valid evidence. Particularly in cases of psychiatric and psychological evidence, courts that once looked solely at the expert’s qualifications to determine the admissibility for expert scientific evidence, now understand that the expert’s qualifications are a necessary but not a sufficient condition for the presentation of accurate expert testimony. Courts increasingly want to know how experts know what they claim to know and whether their methods of knowing meet the hallmarks of good science.Thus, from a legal standpoint, a prerequisite to admissibility of the evidence that serves as a basis for a discussion of the legal implications of MPD/DID is rigorous scientific proof of its existence. Proof of the existence of MPD/DID has not, however, been the subject of rigorous scientific research, but instead has consisted of non-falsifiable clinical experience where the risk of iatrogenesis (i.e., hypnosis and suggestion) is ever present. While these clinical observations and opinions may ultimately be proven valid by subsequent research, there is simply no way to know whether that is so in the absence of rigorous scientific research. If proof of the existence of MPD/DID is clinically but not scientifically grounded, legal rules based upon it are suspect. Moreover, claims of MPD/DID often arise in a legal context where there are significant benefits to be gained from receiving the diagnosis which heightens the importance of rigorous scientific scrutiny.Diagnostic validity and reliability matters in different ways in the forensic context than it does in the therapeutic context. These contextual differences [End Page 59] are reflected in disparate standards for scrutinizing each. There is no threshold requirement, for example, that a psychotherapist prove that a diagnostic category is valid or that a psychotherapeutic treatment used for a person suffering from it is generally recognized as safe and effective before using it; however, there is a threshold requirement of rigorous scientific scrutiny before admission of this information in evidence. If a therapist’s diagnostic hypothesis that there are two personality states influencing a patient’s behavior is not borne out, it can be revised in later sessions. Even if MPD/DID does not exist, treatment that assumes it does may nonetheless be effective because therapeutic outcome is more closely tied to the nature of the therapist-patient relationship than the content of therapy, or because multiple personality states is an effective therapeutic metaphor. Moreover, if the patient is not satisfied that the diagnosis or treatment rendered is helpful, the patient can leave therapy or seek another therapist.In contrast, judicial determinations are a one-shot determination which cannot be revisited in light of subsequently acquired knowledge. The defendant/patient is not free to change courts, or withdraw from the legal proceedings. Thus, it would be entirely appropriate for psychiatrists and psychologists to treat patients presenting symptoms of what they label MPD/DID and for courts to reject exculpatory evidence from psychiatrists and psychologists of that disorder.Related ArticlesFeature Article: Multiple Personality and Moral ResponsibilityCommentary: Commentary by ClarkCommentary: Commentary by ShumanDaniel W.

Snap‐shots of live theatre: the use of photography to research governance in operating room nursing The use of photography is an underreported method of research in the nursing literature. This paper explores its use in an ethnographic research project, the fieldwork of which was undertaken by the first author. The aim was to examine the governance of operating room nursing in the clinical setting and the theoretical orientation was the work of Michel Foucault. The focus of this paper is on (...) how photography was used as a means of data generation. To establish some context we begin by drawing on writers from sociology and anthropology to provide an overview of the status of vision and visual research methods in contemporary social research. We then move to a brief discussion of the uses of photography in social research and the limitations imposed by ethical considerations of its use in clinical nursing settings. As well, the process and approach involved in this research project, and issues of analysis are discussed. Three ‘snap‐shots’ of operating room nursing, taken by participants, are presented. Each is analysed in terms of its contributions to the research process as well as its substantive contribution to the theoretical framework and the research aims. (shrink)

What is wrong with ad hoc hypotheses? Ever since Popper’s falsificationist account of adhocness, there has been a lively philosophical discussion about what constitutes adhocness in scientific explanation, and what, if anything, distinguishes legitimate auxiliary hypotheses from illicit ad hoc ones. This paper draws upon distinct examples from pseudoscience to provide us with a clearer view as to what is troubling about ad hoc hypotheses. In contrast with other philosophical proposals, our approach retains the colloquial, derogative meaning of adhocness, and (...) calls attention to the way in which the context of a theoretical move bears on the charge of adhocness. We also discuss the role of motivations implicit in the concept of adhocness, and the way ad hoc moves draw on theory-internal rationalizations. (shrink)

Most scholars of Islamic intellectual history now agree on the distortedness of the traditional Western portrayal of al-Ġazālī as the defender of Muslim orthodoxy whose Incoherence of the Philosophers was such a powerful critique that it caused the annihilation of philosophical activity in Islamic civilization. Some in fact are coming to the conclusion that al-Ġazālī's importance in the history of Islamic philosophy and theology derives as much from his assiduous incorporation of basic metaphysical ideas into central doctrines of Sunnī kalām (...) , as from his far more celebrated bashing of the falāsifa . What is less well known is that al-Ġazālī's role in the ‘‘philosophizing” of Sunnī theology was not a lonely struggle by a single genius, but part of a broader trend that seems to have begun during Avicenna’s lifetime and that picked up speed in the first and second generations after Avicenna's death in 1037, with the work of al-Ġazālī's teacher, the Aš‘arite al-Gˇuwaynī , as well as of the Māturīdite al-Bazdawī , work that was carried forward by dozens of subsequent members of those two major Sunnī theological schools. It is clear, in fact, that the dividing line between the Sunnī theologians commonly referred to in the later Islamic tradition as mutaqaddimūn , and those referred to as muta’a&hbrevu;h&hbrevu;irūn , lies not with al-Ġazālī but with Avicenna himself, and that the turn in Sunnī kalām was therefore Avicennian, not Ġazālian.

I think that utilitarianism is a good moral theory, and definitely better than its rivals, deontology and teleology. For practical purposes in multicultural contexts, at least, I think that no one should overlook a theory that is able to take into account a variety of ethical views and accommodate the ever-changing facts of the material world. But utilitarianism has a bad reputation in bioethics. It is often seen as the inhumane theory that allows the sacrifice of minorities, the killing of (...) the innocent, and simplistic calculations on the value of life. Hardly anyone cares to remember that most formulations of the theory do not allow these actions. The economic doctrine sometimes labeled as utilitarianism could be guilty as charged, but ethics and economy are not interchangeable words. Also as a theory that can actually propose answers to no-win situations, utilitarianism has been an easy target for criticism. (shrink)

Epistemic contextualism is one of the most hotly debated topics in contemporary epistemology. Contextualists claim that ‘know’ is a context-sensitive verb associated with different evidential standards in different contexts. Contextualists motivate their view based on a set of behavioural claims. In this paper, I show that several of these behavioural claims are false. I also show that contextualist test cases suffer from a critical confound, which derives from people's tendency to defer to speakers’ statements about their own mental states. My (...) evidence consists in results from several behavioural experiments. I conclude that contextualism is an idle hypothesis and I propose some general methodological lessons. (shrink)

In the field of ʿUlūm al-Qurʾān, in which the conceptual framework of the science of interpretation is drawn and the main rules used in tafsīr are discussed, independent books have been compiled since early periods. Some of these works stand out as foundational texts because they make important determinations about the nature, function, methodology, and relationship of the science of tafsīr with other Islamic sciences. The masterpiece entitled Fahm al-Qurʾān by al-Khāris al-Muhāsibī, a scholar of sufism, tafsīr, kalām, and hadīth (...) is one of these books. Al-Muḥāsibī was a writer who lived in a period when philological and Sharīʿah sciences gained a systematic structure and schools were born and developed. Muhāsib'i's multifaceted scholarly depth, the requirements of his time, and the characteristics of his work distinguish Fahm al-Qurʾān from other works in the field in terms of its problematic, content, and style. It can be said that Fahm al-Qurʾān consists of two main chapters. In the first chapter, the issues of kalām, meaning, and reason are subjected to a quiddity inquiry. In the second chapter, the linguistic aspect of kalām is emphasized and the content and style of the Qur'ān are discussed under the headings of muhkam- mutashābih, naskh and üslūb al-Qur'ān. In this work, al-Muḥāsibī suggests that before asking How we should understand the Qur'ān?, the reader should ask What exactly is being understood and what is meaning? The first of these questions includes the question Who am I? While the sources of The Sciences of the Qurʾān mostly focus on how to understand the Qurʾān at the epistemological and methodological level, in Fahm al- Qurʾān, the meaning of understanding the Qurʾān is problematized and a theory of reason and meaning that is competent with moral training is built. Thus, the conceptual inquiries of the work extend to the existential philosophy of the author. Despite these privileges, it is surprising that Fahm al-Qurʾān did not gain a prominent place among the main sources of tafsir methodology in later periods. This may be due to the theorization of a theory of meaning in which moral maturation is placed at the center. In this research, while trying to reveal the original value that Muhāsibī added to the field with Fahm al-Qurʾān, the systematic structure of the science of interpretation, its connection with other religious sciences, the relationship between speech adjective and language were made problematic and tried to be resolved in the context of the research hypothesis. In this context, it has been determined that al-Muḥāsibī's Fahm al-Qurʾān draws the conceptual framework of tafsīr methodology in relation to the authentic structure of the sharī'ah sciences at a very early period. The fact that Fahm al-Qurʾān carries important signs regarding the position of tafsīr in the hierarchy of sciences and its relationship with other sharī'ah sciences increases the value of the work in identifying the codes of the traditional paradigm. In the research, in which induction methods were used in text analysis and deduction methods were used in discourse analysis, it was determined that Fahm al-Qurʾān had a fiction that shapes the traditional paradigm and depicts the authentic structure of religious sciences.

Many recent developments in artificial intelligence research are relevant for traditional issues in the philosophy of science. One of the developments in AI research we want to focus on in this article is diagnostic reasoning, which we consider to be of interest for the theory of explanation in general and for an understanding of explanatory arguments in economic science in particular. Usually, explanation is primarily discussed in terms of deductive inferences in classical logic. However, in recent AI research it is (...) observed that a diagnostic explanation is actually quite different from deductive reasoning. In diagnostic reasoning the emphasis is on restoring consistency rather than on deduction. Intuitively speaking, the problem diagnostic reasoning is concerned with is the following. Consider a description of a system in which the normal behavior of the system is characterized and an observation that conflicts with this normal behavior. The diagnostic problem is to determine which of the components of the system can, when assumed to be functioning abnormally, account for the conflicting observation. A diagnosis is a set of allegedly malfunctioning components that can be used to restore the consistency of the system description and the observation. In this article, this kind of reasoning is formalized and we show its importance for the theory of explanation. We will show how the diagnosis nondeductively explains the discrepancy between the observed and the correct system behavior. The article also shows the relevance of the subject for real scientific arguments by showing that examples of diagnostic reasoning can be found in Friedman's Theory of the Consumption Function. Moreover, it places the philosophical implications of diagnostic reasoning in the context of Mill's aprioristic methodology. (shrink)

Prout's hypothesis was influential in—if not necessary for—the establishment of the atomic weight of oxygen, a figure conclusively demonstrated in 1895. Ironically, the successful determination of oxygen's weight also led to a final refutation of the hypothesis . But more than this, the end of Prout's hypothesis via the determination of oxygen's atomic weight was due to three fundamental changes that characterized the way chemistry was practised and communicated in the late nineteenth century. First, encyclopaedia‐like presentations of (...) past atomic‐weight investigations became the focus in numerous and influential studies. Second, there was a dramatic change in the way professional publications presented investigations and experiments, characterized by experimental detail and apparatus design at the expense of theoretical discussion. Finally, the production of hydrogen became the focus of research, as it was one of the principal components of any investigation into atomic weights. Here I present Prout's hypothesis in its historical context by focusing on these three developments and their influence on the research of Edward Williams Morley. While doing so I also illustrate the way marginalized scientists were able to take advantage of their otherwise dubious position and participate in an active and important role in atomic‐weight investigations.

People do not behave strictly so as to maximize monetary payoffs in ex- perimental games such as Public Goods and Ultimatum games. To explain this ‘anomaly’, behavioural economists have proposed so-called social pref- erence models that try to capture other-regarding preferences as additional arguments of players’ util- ity functions. However, none of the proposed model has successfully ex- plained data across different games. I give a proper diagnosis to this situa- tion by examining Woodward’s methodological critique of the social preference (...) approach. I argue that the problem lies not in external validity as Woodward argues, but internal validity of those experiments. Specifically, I defend the one-shot design as a useful paradigm as long as it is internally valid. (shrink)

This volume, a translation of book 1 of Philo of Alexandria's De vita Mosis, with introduction and commentary, aims to introduce new readers, both students and scholars, to Philo of Alexandria through what is widely considered to be one of his most accessible works and one that Philo himself may have intended for readers unfamiliar with Judaism. The introduction provides historical, intellectual, and religious context for Philo, discusses major issues of scholarly interest, considers the relation of De vita Mosis to (...) the Septuagint, and explores the immediate Nachleben of Philo's works. The author's translation is paired with Cohn's edition of the Greek text, thereby providing not only a rendering of the Greek but also the Greek itself for those who wish to read Philo's own words. The English rendering of the Greek aims at clarity and accuracy while retaining as many of Philo's unique stylistic features as possible. Finally, the notes are designed to elucidate the text, especially for new readers, on a variety of levels: extrapolating on points more fully discussed elsewhere in the Philonic corpus, observing specific divergences from the Septuagint, and suggesting aspects of contemporary historical influence on Philo's retelling of the biblical narrative. The volume serves as a succinct entry into the basics of Philo while also preparing the reader for some of Philo's more challenging works. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:An Ethics of Justice in a Cross-Cultural ContextMichael von BrückThe central thesis of this paper is, primarily, that justice is neither a qualification of actions nor a political expediency, but is an existential reality. This reality is symbolized in different ways depending on religious experience and cultural conditioning. Underlying all concepts and ethics of justice is a dimension of basic insight that is beyond rational quantifying analysis.The semantics of (...) concepts of justice is different in various contexts and meaning systems, that is, in more general political and social contexts and in the rational discourse of philosophy. The general political term for justice is more confusing than helpful for a clear conceptualization; it might be treated more as a symbol in a mythological framework than a concept. In this context justice is defined in terms of what it is not, or metaphorically in differing categories, for example, justice as impartiality, equality. Thus, many programmatic formulae, such as "International Movement for a Just World,"1 express a utopia against the frustration with regard to social, economic, and political conditions and call for action to establish a "just world" without defining what the standard of this action must be in order to qualify as just and what exactly the notion of a "just world" actually might mean conceptually. Certain political actions are condemned from a particular standpoint, but the very foundation of any standpoint remains controversial. "Just" or "unjust" are actions that are determined according to the two standards of an Aristotelian suum cuique and the principle of treating equal cases in equal ways. Here, actions and their results as well as human freedom of action and the respective responsibility are a matter of debate. The problem is how to establish criteria for what is regarded as being "equal."2I suggest that justice can be discussed in two ways: (1) as an agreement or result of negotiation and better insight that is worked out between partners in social processes, and/or (2) as a reflection of the cosmic order, the divine will, or any pre-established harmony that is not negotiable by human beings. Whereas the first assumption is reflected in the theories of Aristotle, Rousseau, John Rawls,3 and others, the second one seems to be one of the basic contents of any religious worldview. Rawls actually constructs his idea of justice as fairness in the line of the familiar theory [End Page 61] of the social contract, following Locke, Rousseau, and Kant. Accordingly, justice is the basic assumption that generates the condition for any further discourse in societies. It is an "original position," an "initial status," the "symmetry of everyone's relations to each other," which, of course, is neither an actual state of historical affairs nor a primitive condition of culture, but a purely hypothetical situation.4 For Rawls, to think justice requires the task to acknowledge interdependencies and mutual dependence of the different factors and actors in societies on the basis of reflexive reason. In religions, however, it is the dharma, the commandment of God, the Tao, or the cosmic harmony or "symmetry" of forces that is the root cause for justice in human relations.In this essay I will not argue any of these positions mentioned above as such but maintain only that any particular discourse depends on communication processes, that is, language and actors. Actors have interests that are mediated through claims. These claims may be compatible or not. However, in both cases they are part of the communication processes itself. And it is in communication that discourses materialize. Therefore, dialogue is the framework for any theory of justice, which may be inclined more to the first or the second position outlined above. Because today, due to economic, political, and cultural circumstances, all discourses are linked to each other, it is in cross-cultural communication and dialogue that a theory of justice has to be worked out. The question is whether justice should be regarded as a precondition for dialogue or a wanted result of dialogue. The hypothesis I want to argue for is that justice is neither only a precondition nor only a result, but that it is the very... (shrink)

By the beginning of the twenty-first century essentialism is giving way to the constructivist paradigm in the field of social sciences and humanities. However, linguistic essentialism survived all the shocks and received a classical form in the Sapir-Whorf hypothesis of linguistic relativism. The application of this hypothesis to the analysis of linguistic communities puts majority and minority languages in different positions: it makes strong languages even stronger, and simply kills small ones. The task of preserving minority languages in (...) programs built using this methodology turns out to be impossible. In our humble opinion, two research paradigms are more adequate for the purpose. One of them is associated with the pragmatic turn in the analytical philosophy of language and represents a transition from the analysis of the structure of the language itself to the analysis of the conditions of communication, taking into account all the sociocultural components of this process. The second methodology is Erving Goff man’s concept of social face and performative behavior. (shrink)

One version of the problem of induction is how to justify hypotheses in the face of data. Why advance hypothesis A rather than B — or in a probabilistic context, why attach greater probability to A than B? If the data arrive as a stream of observations (distributed through time) then the problem is to justify the associated stream of hypotheses. Several perspectives on this problem have been developed including Bayesianism (Howson and Urbach, 1993) and belief-updating (Hansson, 1999). These (...) are broad families of approaches; the citations are meant just as portals. (shrink)

This paper presents arguments in defense of the hypothesis that general proprer names are impossible in the context of Stuart Mill's philosophy of language. My thesis is contrary to John Skorupski's position to this subject. I offer two arguments related, respectively, to two different perspectives: the pragmatic and the systematic. In the first one I analyze the problem of general proper names in the context of natural language. In the second one I discuss this problem in the inner context (...) of Mill's System of logic.O presente artigo apresenta argumentos em defesa da hipótese de que nomes próprios gerais são impossíveis no contexto da filosofia geral de Stuart Mill.

BackgroundAlthough some of the most radical hypothesis related to the practical implementations of human enhancement have yet to become even close to reality, the use of cognitive enhancers is a very tangible phenomenon occurring with increasing popularity in university campuses as well as in other contexts. It is now well documented that the use of cognitive enhancers is not only increasingly common in Western countries, but also gradually accepted as a normal procedure by the media as well. In fact, (...) its implementation is not unusual in various professional contexts and it has its peak in colleges. Even when certain restrictions in the legislation of a country are indeed in place, they are without doubts easy to overcome. The legitimacy and appropriateness of such restrictions will not be the focus of our investigation.DiscussionOur concern is instead related to the moral and social reasons to publicly acknowledge the use of cognitive enhancers in competitive-selective contexts. These reasons are linked to a more neutral analysis of contemporary Western society: it is a fact that an increasing number of competitive-selective contexts have a substantial number of contenders using cognitive enhancers.SummaryThrough the use of five explicative examples, in this paper we want to analyse the problems related to its use. In particular, it will be our aim to show the tension between one of the main argument used by bio-liberals and the actual implementation of the drugs in competitive, or semi-competitive contexts.

Fodor and Pylyshyn's critique of connectionism has posed a challenge to connectionists: Adequately explain such nomological regularities as systematicity and productivity without postulating a "language of thought" (LOT). Some connectionists like Smolensky took the challenge very seriously, and attempted to meet it by developing models that were supposed to be non-classical. At the core of these attempts lies the claim that connectionist models can provide a representational system with a combinatorial syntax and processes sensitive to syntactic structure. They are not (...) implementation models because, it is claimed, the way they obtain syntax and structure sensitivity is not "concatenative," hence "radically different" from the way classicists handle them. In this paper, I offer an analysis of what it is to physically satisfy/realize a formal system. In this context, I examine the minimal truth-conditions of LOT Hypothesis. From my analysis it will follow that concatenative realization of formal systems is irrelevant to LOTH since the very notion of LOT is indifferent to such an implementation level issue as concatenation. I will conclude that to the extent to which they can explain the law-like cognitive regularities, a certain class of connectionist models proposed as radical alternatives to the classical LOT paradigm will in fact turn out to be LOT models, even though new and potentially very exciting ones.

The article deals with the mythological creativity of G.R.R. Tolkien as a socio-cultural phenomenon associated with the values of European culture. The author proceeds from the hypothesis that the myth is the embodiment of social identity, this function it retains after the loss of its ideological functions. The revival of literary mythology in the XIX-XX centuries there is an attempt to update this feature of the myth. The success of the literary myth is due to the fact that he (...) was able to absorb and Express the basic values of society. Tolkien’s work is one of the successful examples of the literary embodiment of socially significant values, combining both traditional values and value formations characteristic of the modern era. The article shows that Tolkien’s work has organically absorbed the pagan basis, the Christian attitude, and the values characteristic of the XX century. Pagan heroic principle, Christian mercy, the idea of freedom, democracy-all this is organically intertwined in the works of Tolkien, their success is due to the harmony of the whole range of social attitudes represented in the European consciousness of the mid XX century. Currently, the decline in interest in Tolkien is a reflection of the change of value preferences of European culture. (shrink)

Freedom of Religion, Institution of Conscientious Objection and Political Practice in Post-Communist Slovakia1 The example of Slovakia is used to show how one of the post-socialist countries failed in fulfilling the demanding task of securing freedom of religious belief (including the right to conscientious objection) and, at the same time, securing all other human rights. An analysis of the methods used for changing the policies of pluralism and neutrality of the state into a policy of discrimination (e.g. concerning the registration (...) duty for churches) was carried out, followed by an analysis of a mechanism used for guaranteeing freedom of conscience of the members of the Catholic Church (the so-called Vatican Treaty). The treaty violates the prohibition of discrimination against women, because it makes it more difficult for them to have access to some health care services. Our hypothesis states that the hurriedly introduced right to conscientious objection is misused in this context as a means of regulating the politics of reproduction. In general, the re-Catholisation of the Slovak Republic follows two aims—to help in the fight for votes in the elections (because 70 % of Slovaks declare their religion to be Catholic), and to improve demographic development in the Slovak Republic (declared to be catastrophic by the Catholic Church), through hindering free access to abortions.

A substantial amount of recent work in natural language generation has focused on the generation of ‘‘one‐shot’’ referring expressions whose only aim is to identify a target referent. Dale and Reiter's Incremental Algorithm (IA) is often thought to be the best algorithm for maximizing the similarity to referring expressions produced by people. We test this hypothesis by eliciting referring expressions from human subjects and computing the similarity between the expressions elicited and the ones generated by algorithms. It turns out (...) that the success of the IA depends substantially on the ‘‘preference order’’ (PO) employed by the IA, particularly in complex domains. While some POs cause the IA to produce referring expressions that are very similar to expressions produced by human subjects, others cause the IA to perform worse than its main competitors; moreover, it turns out to be difficult to predict the success of a PO on the basis of existing psycholinguistic findings or frequencies in corpora. We also examine the computational complexity of the algorithms in question and argue that there are no compelling reasons for preferring the IA over some of its main competitors on these grounds. We conclude that future research on the generation of referring expressions should explore alternatives to the IA, focusing on algorithms, inspired by the Greedy Algorithm, which do not work with a fixed PO.

A model of inductive inquiry is defined within the context of first‐order logic. The model conceives of inquiry as a game between Nature and a scientist. To begin the game, a nonlogical vocabulary is agreed upon by the two players, along with a partition of a class of countable structures for that vocabulary. Next, Nature secretly chooses one structure from some cell of the partition. She then presents the scientist with a sequence of facts about the chosen structure. With each (...) new datum the scientist announces a guess about the cell to which the chosen structure belongs. To succeed in his or her inquiry, the scientist’s successive conjectures must be correct all but finitely often, that is, the conjectures must converge in the limit to the correct cell. Different kinds of scientists can be investigated within this framework. At opposite ends of the spectrum are dumb scientists that rely on the strategy of “induction by enumeration,” and smart scientists that rely on an operator of belief revision. We report some results about the scope and limits of these two inductive strategies. (shrink)

This article proposes a semio-rhetorical epistemology for visual documents, one capable of accounting for both their internal configuration, which we shall call the compositional dimension, and their persuasive force within public space, or their rhetorical dimension. The field of reference will be that of identity-related images on social networks, because compared to other kinds of images, such as artistic or professional ones, they adopt new compositional solutions and new dynamics of circulation. To test this theoretical framework, we will conduct an (...) analysis which has never been carried out in semiotics and which, as far as we know, remains very rare even in the overall field of visual studies, that is, the analysis of the profile of an Instagram influencer’s visual production, that of Canadian artist Rupi Kaur. Taking into account the flow of images shared over time, we will focus primarily on the compositional dimension that articulates the specificity of the language of images. The most appropriate model for investigating social network photos seems to be that of the portrait, thanks to which we will identify a first series of regularities and deviations. Secondly, we will turn towards the rhetorical dimension – the persuasive strategies found within, through, and towards images – focusing on the analysis of a single photo: on the one hand, it is a shot which presents greater compositional richness than others; on the other hand, it has greatly impacted the notoriety of the influencer, due to the censorship incurred on Instagram, its abundant coverage by traditional media, and the heated debate it triggered on social media. We will thus propose a reinterpretation of Paul Ricœur’s theory of identity in order to balance the rhetorical and the compositional dimensions through a unitary theoretical hypothesis. Visual identity on social networks is always the result of a negotiation between two opposite tendencies: on the one hand, the experiential pressure expressed through images related to the body and everyday practices; on the other, the algorithmic pressure due to the delegation of the management of identity to software. The case of Rupi Kaur is a rare example of a critical mediation between these two pressures and helps us build a methodology for the examination of images belonging to other social domains. (shrink)

There are currently serious concerns that published scientific findings often fail to be reproducible, and that some solutions may be gleaned by attending the several methodological and sociological recommendations that could be found in the literature. However, researchers would also arrive at some answers by considering the advice of the philosophy of science, particularly semantics, about theses on truth related to scientific realism. Sometimes scientists understand the correspondence thesis of truth as asserting that the next unique empirical confirmation of a (...) hypothesis suffices to attribute truth to it provisionally. Such empiricist bias is not necessarily at the core of CTT, but Mario Bunge proposed the synthetic thesis of truth, based on CTT, to explicitly avoid the bias. STT requires considering a hypothesis corroborated, both by purely empirical confirmation and external consistency or compatibility with the bulk of existing background knowledge. While a capricious understanding of CTT could be rigged to recommend the “one shot game” in hypothesis testing, STT clearly demands the use of multiple approaches, empirical as well as theoretical, and it asserts that a scientific test is effective to the extent to which it is neither purely empirical, nor viewed in isolation. Pattern consistency together with an understanding of causal relations make confirmed hypotheses robust and more reliable. The militancy of the double mechanism of hypothesis control of STT can help mitigate the reproducibility crisis. Earl Werner’s research program in community ecology is an example of the use of STT criteria, which leads to the development of reliable, cross-checked, ecological results, with high predictive capacity.

Charles Peirce’s model of inquiry is supposed to demarcate appropriate methods of inquiry from specious ones. Cheryl Misak points out that Peirce’s explicit account fails, but can nevertheless be rescued by elements of his own system. While Misak’s criticism is a propos, her own attempt to fortify Peirce’s account does not succeed, as it falls prey to the same criticism she raises against Peirce’s explicit account. The account provided in this paper—the ‘open path’ alternative—draws from Peirce’s corollary to his “first (...) rule of reason”, that one should not block the road to inquiry. The ‘open path’ account is able to withstand Misak’s objections, and when combined with other aspects of Peirce’s work, shows us why the optimal way to conduct inquiry is to follow the path of greatest resistance. Inquiry, however, is rarely conducted in optimal conditions. Actual, constrained conditions of inquiry require a measure of economy in terms of what can be reasonably pursued and how. The question, then, is how to conduct our inquiries so that they are as nearly optimal as possible given actual constraints. As a working scientist, Peirce was acutely aware of the need to economize in research. Nicholas Rescher has recognized this issue’s significance for Peirce, and noted its neglect in discussions of Peirce’s work. One issue that has been largely neglected in the literature on Peirce is what specifically he recommends, based on considerations of economy, for how to go about gathering evidence. Kronz & McLaughlin points out that Peirce’s primary recommendation is that in gathering evidence relevant to a particular hypothesis we should test for empirical consequences that would not have been expected otherwise. The view that is developed in this paper is that economy in research, according to Peirce, follows the general line of his theory of inquiry. Peirce’s theory of inquiry implies that pursuit of truth requires maximizing resistance. I argue that his considerations about how to navigate within the constraints introduced in the context of actual research are also best understood as recommendations for maximizing resistance.

Anecdotal evidence suggests that participants in conversation can sometimes act as a coalition. This implies a level of conversational organization in which groups of individuals form a coherent unit. This paper investigates the implications of this phenomenon for psycholinguistic and semantic models of shared context in dialog. We present a corpus study of multiparty dialog which shows that, in certain circumstances, people with different levels of overt involvement in a conversation, that is, one responding and one not, can nonetheless access (...) the same shared context. We argue that contemporary models of shared context need to be adapted to capture this situation. To address this, we propose “grounding by proxy,” in which one person can respond on behalf of another, as a simple mechanism by which shared context can accumulate for a coalition as a whole. We explore this hypothesis experimentally by investigating how people in a task-oriented coalition respond when their shared context appears to be weakened. The results provide evidence that, by default, coalition members act on each other's behalf, and when this fails they work to compensate. We conclude that this points to the need for a new concept of collective grounding acts and a corresponding concept of collective contexts in psycholinguistic and semantic models of dialog. (shrink)
